Quick assessment
Affected
patriksimek vm2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
vm2 在 3.11.6 之前的版本未能对 、 和 的构造函数强制实施 ，这使得攻击者能够分配任意数量的主机内存。攻击者可以利用这些 V8 内部函数绕过缓冲区分配上限，从而耗尽宿主进程的内存并触发内存不足（out-of-memory）状态。

Vulnerability Title
vm2 before 3.11.6 Memory Exhaustion DoS via bufferAllocLimit Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
vm2 before 3.11.6 fails to enforce bufferAllocLimit on ArrayBuffer, SharedArrayBuffer, and TypedArray constructors, allowing attackers to allocate arbitrary host memory. Attackers can bypass the buffer allocation cap by using these V8 intrinsics to exhaust host process memory and trigger out-of-memory conditions.
